Ideally all of your speaker channels should be balanced so that they are all at the same volume level at the spot where your ears would be under normal listening/viewing conditions. With most set-up procedures you would sit where you normally sit and either guestimate this with your own ears (difficult in my opinion) or use an SPL metre to make life easier and more accurate.

Volume on the amp should be ideally set to '0' decibels or any other fairly mid to high range point: your 'reference' level.

You then balance the volume to either 75db per channel or 85db if using the Avia set-up tones. Your sub may need to be increased or decreased according to your own taste/neighbours.
